Abstract: The Datagram Congestion Control Protocol (DCCP) was designed to provide congestion control for unreliable applications, such as voice-over-IP and IPTV. But the current congestion control mechanisms of DCCP do not have the ability to support Quality of Service (QoS) features. This paper aims to design an end-to-end QoS-aware congestion control mechanism for DCCP based on theory. In particular, we design an end-to-end traffic control mechanism to support Real-time Delay Adaptive and Real-time Rate Adaptive applications. The mechanism possesses several provable properties, including friendliness to TCP, stability, and optimality. The experimental results show that the proposed mechanism can provide minimum rate guarantee for real-time applications and maintain a lower packet drop ratio.
